To all whom t concern:

Be it known that I, FREDERICK C. SMITH, a citizen of the UnitedStates, residing at Port Arthur, in the county of Jefferson and State of Texas, have invented certain new and useful Improvements in Filling-Machines, of which the following is a specifica.- tion.

This invention relates to new and useful improvements in filling machines.

The object of the invention is to provide a machine of the character described which will automatically transfer liquids preferable in predetermined,quantities from one receptacle to another and isparticularly constructed for the purpose of transferring such liquids as oils from a receiving vat or receptacle into cans in which the same is marketed.

Another object of the invention is to proy vide a device of the character described whereby a plurality of cans may be simultaneously lilled.

A further feature of the invention resides in the. provision of means whereby a predetermined quantity of liquid will be transferred into each can or container.

A further feature of the invention resides in the provision of a mechanism-whereby the liquids will be transferred from the receiving receptacle into the respective cans automatically.

With the above and other objects in view, the invention has particular relation to certain` novel features of construction, and operation, an example of which is given in thisv specificationl and illustrated in the accompanying drawings, wherein- Figure l'is a front elevation of the device, partly in section.

Fig. 2 is an end view thereofshown partially in section.

Fig. 3 is a plan View thereof.

Fig. t is a plan view of a rotatable platform used in connection with the device for carrying the cans into position to `be filled.

Fig. 5 shows a fragmentary side elevation of said platform showing also the 4means for locking the same in stationary position while the cans are being filled.

Figs. 6 and 7 show, respectively, slde and front elevations of vertically movable funnels, forming a part of the device. i

Figs. 8 and 9, show, respectively, side an front elevations of the transferring buckets.

Figs. 10 and l1 show, respectively, -side and front elevations of displacers which are used in connection with said buckets for governing the capacity thereof and the amount of liquid to be transferred thereby.

Fig. 12 shows a detached detail view of Aof the supporting frame for the transferring buckets.

Referring now more particularly to the drawings, wherein like numerals of reference designate similar parts in each of the figures, the numeral 1 refers to a receiving or supply tank which may be made of any desired capacity and is preferably constructed of sheet metal or some other like durable material.

This tank is preferably of considerable length, and may be of approximately equal width and depth and is provided as a temporary receiving receptacle for the liquid before it is transferred into the containers to be lled. y

A supply pipe Q is provided which leads from the source of supply, (not shown) and discharges into the bottom of tank l. The supply pipe has a regulating valve 3, of suitable construction, which may be controlled by the upward 0r downward movement of the lever 4, which is rigidly attached at one endto the valve stem 3a. `Within the tank 1 is a float 5 attached to the free end of the rod 6. 'The other end of this rod 6 is rigidly attached to the shaft 7 which extends through the rear wall of the tank 1 and rotates in a suitable bearing therein and the otherl end of which has an arm 8, one end of which is rigidly secured to said shaft.

The free ends of the arms 4 and 8 are connected by a link 9, the ends of which are pivoted t0 the free ends of said arms, respectively. As the tank 1 is emptied, the float 5 is lowered which operates through the mechanism just described to lower the arm 4 and open valve 3 to permit admission of oil from the supply to the tank l.

As said tank fills with liquid, the float 5 is elevated, which in turn operates through the mechanism described to elevate the arm 4; and close the valve 3 and cut olf the supply of liquid and thus prevent the tank 1 from overflowing.

It is thus apparent that as the liquid is transferred from the tank 1 into the containers to be filled, the valve 3 will be automatically opened and a new supply provided and it is further apparent that the valve regulating mechanism operates as a safety device to cut ofi the fluid supply when the tank 1 has been filled. y I

j. rranged above the device is a hood 10 som-what longer and wider than the tank 1. rlhis hood is not indispensable, but may be used when desired, particularly when volatile oils, such as gasolene and other similar oils are being filled, to confine the fumes and gases given off by the oils and to prevent their escape and distribution throughout the room where the device is used. Y Y,

In case these gases become ignited, the hood may be filled with steam from a suitable steam pipe (not shown) and the iames thus smothered. This method of extinguishing the flames would not be possible if the gases were not confined.

The tank 1 is supported upon a -supporting frame 11 and is elevated to a convenient height and arranged within the tank is a plurality of buckets 12. The buckets are preferably arranged side by side lengthwise of the tank and are clamped between chan-l nel irons 13 and 14 arranged on opposite sides thereof and extending lengthwise with respect to the tank 1 as shown in- Fig. 16, and in dotted-lines in Figs. 1 and 13. The buckets 12 are thus'held in a fixed position relative to each other and are movable together as will be hereinafter described.. Any desirable number of buckets may be used, depending upon, their size and the length of the tank, and the channel irons .13 andl 14C are secured together by end braces 13', 13', one of which is shown ink Fig. 16. The buckets, together. with their supporting frames, are preferably held suspended by means of links 15 and 16, as shown in Fig." 2. There aretwo of each of these links, one at each end of the tank and said links are each pivoted at one end to a plate 17 carried by the end ofthe tank 1 and at their other end are pivoted to the end braces 13, above described. Each ylink 16 is somewhat shorter than its corresponding link 15 and is pivoted to the brace 13 near the top of the latter and each link 16 is pivoted to its brace 13- near the bottom thereof, so that as the buckets 12 move upward they are caused to tilt forward so as to discharge the contents thereof. Each bucket is providedv with 'a forwardly proecting spout 18 by means of which .the

liquid is directed fromthe bucket into the receiving funnel as will hereinafter be described. Y

Each bucket is provided with a displacer 19 formed preferably of sheet metal and entirely inclosed so as not to fill with liquid. V

21 which receives rotation from a suitable motor, (not shown). Thisfshaft has a spur gear wheel 22 fixed thereon which meshes with a spur gear wheel 23 fixed upon the shaft 24, which is rotatably mounted in bearings 25, 25, and runs counter to the drive shaft. t

rlhe shaft 24 carries a rigidly mounted spur gear wheel 26 see Fig.y 2, which meshes shaft 28. The shaft 28 rotates in the bearings 29, 29, 29 alined with each other over .the tank and each end of the shaft 28 has a rigidly mounted arm 30. The outer'ends of each of the arms 30 are pivoted, respectively, to one'end of one ofthe links 31 and the other ends of these respective links are pivoted to the corresponding end braces 13, near their lower sides.

As rotation is imparted to the shaft 28, through the gear mechanism just described, the arms 30 and links 3 l natively elevate and low r the buckets 12. When the buckets 12 are lowered, they are submerged in the liquid in the tank 1 and are filled therewith and when said buckets are elevated, the links 15 and 16 will operate to tilt them so as to discharge the liquid into suitable liquid conveyers which m'ay be the funnel 32.

The links are so positioned that the buckets 12 will be lifted vertically from the liquid so as to be exactly full until they are elevated above and ready yto discharge into the funnels 32.

These funnels are arranged side by.v side and are fixed to the braces 33 and 34, extending lengthwise of the tank, the former of 'which extends along the front side of the funnelsv andthe latter of which is secured underneath the funnels so that said funnels will be secured ytogether and fixed in their relation to each other. 'There is a funnel for each bucket and the corresponding funnels and buckets are fixed in corresponding relation to eachother.

The front wall of the `tank 1 is formed ir two parts, the upper portion projecting out farther than the under portion so as to leave an opening in the front wall extending from end to end of the tank, and the upper portion of eachV funnel has an upwardly prowith a spur gear wheel 27 fixed upon the operate to alterf Lezama.

jecting shoulder 35, 'which rests against/the inner surface of the upper portion of the front wall of the tank.

Each funnel 32 has a down spout d6` having a tapering discharge nozzle 37 through which the liquid is discharged into the containers 38 carried by the rotatable platform BSL The funnels 82 are arranged to be lowered and elevated so that the nozzles 37 may be projected into and Withdrawn from the openings 40, provided for the purpose, in the tops of the containers.

Y Rotatably mounted in the bearings 41, .41 underneath the ends of the tank l is a shaft 42 and fixed to the respective ends of this shaft are the arms 43, 43, whose free ends,

respectively, are connected to the brace 34 upwardly from one end of the shaft 42 and rigid therewith is an arm 45 and in front of the device is a hand lever 48 pivoted at its lower end to a stationary support 46a.

This lever46 is connected to the free end of the arm 45 bymeans of a link 47. When the lever 46v is manipulated in one direction, that is, toward the tank, it operates through the link 47 and the arm 45 to partially turn the shaft 42 and the freeends of the arms 43 are elevated and operate through thev links 44 to elevate the funnels 352 and with; draw the nozzles 37 from thccontainers 38. `Wherrthe lever 46 is manipulated in the opposite direction, a downward movement is in like manner transmitted to the funnels 32 and the nozzles il? are projected into the openings 40in the tops of the containers 38.

Each end of the tank is provided with a pulley 48 and a cable 49 is passed over each pulley, one end of said cable being attached to the frame Work 'supporting the funnels and the other end having a weight 50. These weights are provided to balance the funnels and make them the .more easily elevated. Any other preferred balancing device, however, may be used if desired. n

In Figs. 13, 14 and 15, l have shown a modified form of the device in whichthe drive shaft 28 carries a ri; diy mounted bevel gear wheel 51 which mesheswith a gear wheel 52 rigidly mounted on the shaft 58, which is operatively connected with a motor, (not shown).

in the modified form shown in said Figs. 13, 14 and 15, a mechanism for dumping the buckets 12, somewhat different from that shown in Figs. vland 2, is employed. This construction will now be described :m

The inner side of the end walls of the tank l are provided with upwardiy entending guide channels .34 and The upper end of the channel 534 has a decided or abrupt for "ard curve .it and the upper end of the channel 55 has also a forward curve 57, but more gradual than the curve 56. l-rojccting from the respective ends of the frame work supporting the buckets l2 are short shafts or studs 58, 58 and 59, 59, shown in full lines at one end of Fig. 13, and in dotted lines at the other end of said figure and in Fig. 14. The free ends ofthe shafts 58 project into the corresponding channels 54 and the free ends' of the shafts project into the corresponding channels rlhe projecting ends of said shafts preferably have anti-friction rollers which operate against the sides of said channels.

The shafts 59 are arranged near the top and frontside ofthe buckets 12 and the shafts 58 are arranged near the bottom and rear side thereof and as an upward pull is exerted through the links 31, the anti-fricy tion rollers of these respective shafts travel by means of the links 44, 44. Projecting in the channels and 55 and when the forward curves of said channels are reached,

the buckets will be tilted forwardly and the spouts 18 of said buckets projected into the funnels 32 and the contents of said buckets thereby'discharged into the funnels.

The operation of the two forms of the device shown is substantially the sameand the construction is the same except with vrespect to the di'erences pointed out.

The operation of the invention is as follows The containers 38, provided to receive the liquid, are arranged on the rim of the ros tatable platform 89, as shown in F 4so that they will be inexact alinement, andthe platform is then rotated so as to bring the containers directly under the funnels 3Q, the nozzles 37 of said funnels alining overl the holes 40 in the tops of the containers. `While the containers are being'iilled the platform is held against rotation by means of the mechanism shown in Fig. 5. This mechanisni7 however, forms no part of the invention and a specific description thereof is not deemed necessary.

W hen the containers are alined under the funnels 32 the hand lever 4G is manipulated so as to lower said funnels and project the nasales 37 thereof into the corresponding i containers.

The machine is so geared. that ample time is provided between discharges of liquid from the buckets to enable the operator to elevate the funneis above a row of containers j and to thereafter rotate the platform 39 to isa '39 manually and the platform is rotated manually and the tunnels 32 are also ele- Vated and lowered manually but the buckets are elevated and lowered automatically and the containers must be brought into position underneath the tunnels and said tunnels lowered with regularity so as to be in position to receive the fluid discharged from the buckets at regular intervals. i

1While l have shown only two forms of this device it is readily apparent that the mechanical construction may be varied and yet the same results obtained and I desire to reserve the right to make mechanical variations in the construction of the device so long as l do not depart from the scope of the appended claims.

lilfliat I claim is l. In a illing machine, a tank formed at its top ivith laterally extending flanges, a bearing-frame supported upon said flanges, a rotary shaft journaled in said frame and .carrying spaced crank arms, a plurality of connected buckets, a plurality of links depending` within the tank and pivotally connecting said crank arms with the buckets whereby thelatter may be alternately raised and lowered, and means for tilting the buckets when they are raised to a predetermined height.

2. in a filling machine, the combination with a tank adapted to maintain therein apredetermined height of liquid and a vplurality of connected buckets located therein,

of means for yraising and lowering said buckets, a series of connected tunnels communicating with the tank above the liquid therein, and means :tor raising and lowering with an upwardly extending guiding projection, and means for supporting the funnels including a plurality of spaced cables,

` each cable being led over an idler pulley and carrying a counterweight, said idler pulley being located back of the said upwardly en tending guiding projections and the cables being` connected with the tunnels below said projections, so that the latter are maintained Ain abutment with the inner Wall of the tank.

In testimony whereof I have hereunto signed my name in the presence. of two subscribing Witnesses.
